This April, the Razer Nexus (Free) app received an update adding support for the then-unannounced Razer Kishi Ultra controller. This controller boasts features like customizable analog stick deadzones and more. Since its release, the Kishi Ultra has proven its compatibility extends beyond just phones. While it's currently the priciest mobile controller on the market, its feature set justifies the cost for certain devices. Having extensively used the Razer Kishi and Backbone One (including their USB-C iterations), I initially felt no need for a new controller. However, the Razer Kishi Ultra proved me wrong, much like the Hori Split Pad Pro did for the Nintendo Switch years ago.
Razer Kishi Ultra – Package Contents
The Razer Kishi Ultra's packaging included the controller, several sets of rubber cushions (for various devices), stickers, and an instruction manual. At $149.99, a carrying case or pouch would have been a welcome addition. However, the box and controller packaging maintain Razer's usual high quality.
The rubber cushions are paired and labeled for iPhone (Pair A), iPad Mini 6th generation (Pair B), and Android (Pair C). These are unnecessary if using a case.
Razer Kishi Ultra Compatibility – iPhones, Cases, Android, and iPad Mini
Unlike many telescopic controllers that only support iPhones and Android devices, the Razer Kishi Ultra also works with tablets like the iPad Mini 6th generation. While some recent telescopic controllers offer Bluetooth connectivity, the Kishi Ultra's USB-C connection appears to offer superior compatibility. For this review, I tested it on my iPhone 15 Pro, iPhone 14 Plus, and wired to my iPad Pro. While I didn't test Android or Windows compatibility directly, I did try it wired on my Steam Deck. It was recognized as a generic Xbox gamepad, functioned well in NBA 2K25, and provided decent rumble in games like Bakeru.
Razer Kishi Ultra Buttons, D-pad, and Triggers
Before discussing new features, let's assess the controller's feel and performance. I initially had concerns about the d-pad, but it performed admirably in games like Garou: Mark of the Wolves ACA NeoGeo, Hades, and Hitman Blood Money Reprisal. The shoulder buttons and triggers function as well as those on Razer's previous controllers. The analog sticks are comfortable and smooth, while the face buttons are clicky, though with more travel than expected compared to the original Razer Kishi.
After extensive use, including several multi-hour gaming sessions (like Zenless Zone Zero while charging via passthrough), I have no complaints about the d-pad, buttons, or triggers.
The textured finish, while not rubbery, provides excellent grip and remains comfortable even during extended use. While I'm not usually a fan of Chroma lighting, I would have preferred the lights to dynamically reflect on-screen gameplay, similar to the Razer Kitsune.
Razer Kishi Ultra – New Features
The Kishi Ultra's main selling point is its full-size form factor. Unlike the more compact designs of previous Razer controllers or the Backbone One, the Kishi Ultra feels like a full-sized console controller with the phone nestled in the center. This might not appeal to those seeking a compact solution, but it's not designed to be one. This full-size design makes it the most comfortable mobile controller I've used.
Other features include Chroma customization via the app, haptics (Android and Windows), and virtual controller mode (Android only). The virtual controller mode is beneficial for Android games that lack controller support outside of iOS.
Additional features include a 3.5mm headphone jack, 15W passthrough charging, and L4 and R4 shoulder buttons.
Razer Kishi Ultra iOS Limitations – Haptics and Virtual Controller Mode
Haptics and virtual controller mode are currently exclusive to Android (and Windows for haptics). While I'm not overly concerned about virtual controller mode, I hope Razer will implement haptics support for iOS in future updates.
Razer Kishi Ultra Price – Is It Worth It?
For many, a wireless PS5 or Xbox controller offers a superior and cheaper wireless gaming experience on iOS. However, if you prefer a telescopic controller that attaches directly to your phone, the Razer Kishi Ultra's $150 price tag is significantly higher than the $99.99 price point of competing controllers. Is the extra cost justified? If you're satisfied with the Razer Kishi or Backbone One, the upgrade is worth it for the enhanced comfort. However, the lack of haptics on iOS diminishes the overall experience compared to Android.
Long-term joystick drift remains a concern, though it hasn't yet been observed in my testing.
Razer Kishi Ultra – The Best Mobile Controller in 2024?
Compared to the more compact Razer and Backbone controllers I've used, the transition to the full-size Kishi Ultra has been interesting. Similar to the Hori Split Pad Pro, I now find myself wanting both a full-size and a more compact controller for my iPhone.
The Razer Kishi Ultra is undeniably the most comfortable mobile controller I've used, but its size makes it less travel-friendly. I'm concerned about its portability unless I use the original box for transport. It's unlikely to replace my Kishi or Backbone One for travel, but it's my go-to controller at home.
At this price point, hall-effect analog sticks would have been a welcome addition. I've experienced drift issues with other controllers, and while it hasn't occurred with the Kishi Ultra (or my original Kishi), it's a potential long-term concern.
Having reviewed Backbone One and Razer Kishi models, I'm eager to explore the GameSir lineup.
Razer Kishi Ultra 2 Wishlist
For a future iteration, hall-effect sticks are a top priority. I'd also like smoother edges, particularly around the passthrough charging port. While I appreciate the L4 and R4 buttons, I prefer bottom-mounted paddles for a more natural feel. Adding L5 and R5 paddles with remapping options in the Razer Nexus app would be excellent. Finally, including a carrying case would greatly enhance the overall package.
Razer Kishi Ultra Review Summary
If you prefer the feel of full-sized controllers like the PS5 or Xbox controllers and find compact mobile controllers uncomfortable, the Razer Kishi Ultra is ideal. Its comfortable grip, excellent d-pad, and face buttons are its strengths. The lack of full feature parity on iOS is a drawback, but it's a significant addition to the mobile gaming market. A carrying case would be a valuable addition.
